Substitute Part Grouping Explanation

Substitute parts for the ERJ-S03F17R4V are qualified based on the following criteria:

• Identical resistance value: 17.4 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.1W (1/10W)
• Same package configuration: 0603 (1608 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Equivalent automotive qualification: AEC-Q200
• Matching RoHS compliance: ROHS3 Compliant
• Identical moisture sensitivity: MSL 1 (Unlimited)

All substitute parts meet these electrical and mechanical parameters, enabling direct functional replacement in automotive and industrial applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts—ERJ-S03F17R4V, ERJ-3EKF17R4V, CRCW060317R4FKEA, and RMCF0603FT17R4—are active production components with ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Preferred manufacturer qualification within supply chain
• Physical dimension tolerances for specific PCB layout constraints
• Existing design documentation and qualification history

The ERJ-3EKF17R4V offers the highest inventory availability at 61,461 pieces, supporting high-volume production schedules. The CRCW060317R4FKEA from Vishay Dale provides an alternative from a different manufacturer base. The RMCF0603FT17R4 from Stackpole Electronics represents a third-source option. All parts maintain identical electrical performance and automotive compliance ratings.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF17R4V replace ERJ-S03F17R4V directly?

A: Yes. Both parts share identical electrical specifications (17.4 Ohms ±1%, 0.1W, ±100ppm/°C), package configuration (0603), composition (thick film), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive rating. The primary difference is the series designation (ERJ-3EK versus ERJ-S03) and higher inventory availability for the ERJ-3EKF17R4V.

Q: Are cross-manufacturer substitutes (Vishay Dale, Stackpole) compatible?

A: Yes. CRCW060317R4FKEA and RMCF0603FT17R4 meet all specified electrical and mechanical parameters. Physical dimensions vary slightly within tolerance (length 1.55mm to 1.60mm, height 0.50mm to 0.55mm), but remain compatible with standard 0603 PCB footprints. All parts carry AEC-Q200 qualification and ROHS3 compliance.

Q: What determines substitution eligibility for this 17.4 Ohm resistor?

A: Substitution is based on matching resistance value (17.4 Ohms), tolerance (±1%), power rating (0.1W), package (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Deviations in any of these parameters disqualify a part from direct substitution.

Q: Does the anti-sulfur feature of ERJ-S03F17R4V affect substitution?

A: The anti-sulfur feature is specific to the ERJ-S03F17R4V series. Substitute parts (ERJ-3EKF17R4V, CRCW060317R4FKEA, RMCF0603FT17R4) do not explicitly list this feature. If anti-sulfur construction is a design requirement, the ERJ-S03F17R4V should be retained as the primary choice.

Q: Are all parts suitable for automotive applications?

A: Yes. All four parts carry AEC-Q200 automotive qualification, supporting use in automotive-grade circuits. MSL 1 (Unlimited) rating indicates no moisture sensitivity restrictions for storage or handling.
